We're currently working on Winnie's Hole, a game about being a symbiotic virus in Winnie.
Spread the virus to capture cells in his body which mutate and evolve your host, as you adventure through a dark reimagining of the classic Winnie world inspired by Brother's Grimm fairy tales and Nickelodeon cartoons.
We often start with game mechanics and knew we wanted to make a game about building a monster, which is played by building. We'd been prototyping mechanics for months without really finding a direction that was working... It seemed like a good direction would be playing as a virus, and we had this block placement minigame which felt kind of interesting. Eventually we took a break from making this more serious virus growing game to do a gamejam with the classic Winnie content, which had entered public domain that year.
We tried combining these ideas and Winnie turned out to be a great comedic contrast to a virus, and the simpler art style worked really well with the way we'd set up mutations. The goal of a virus is to survive and propagate, and a symbiotic virus will benefit its host. Winnie, being a bit clumsy and naive, doesn't even really understand he's infected at first so the situational comedy became really fun to write for and the project kept growing from there.
